i think its froyo because of working cam/camcorder
sounds like you might have a winner here. i am working on porting a rom from the captivate myself...
however you have me a little confused.... why would you port motoblur anything?
most everyone that i talk to that has a moto phone... doesnt want it. it may be hard to sell the idea of motoblur to anyone especially if they know how much crap it is....
its like timescape and mediascape... mainly useless and irritating... ( this is just my opinion) and am just curious why you would like to port that to an x10?
sorry but some screens?
thank's
@OP
i had a milestone... which variant is this rom based on "OH!NO!" / "ShadowMOD" / "HoBoMOD" ????
also some screenshots would be nice...
by the way, all of us should stay together as a team make sure we exist..
@ mods
Please clean this tread.
Give the OP a least a change to promote his ROM
PS this tread is reported to the mods for cleaning!!!
Lets stop this and of you want arguing. There is a nice tread in the general place.
(I think we all know what tread )

Stop. We're done with this. Please go to the general section if you have problems, we have a huge thread there.
OP, I can't wait for your ROM and I wish you the best!
I've been through this same thing... even though you don't have to as the sources being talked about can't be altered and taken ownership of... if you did use his sources just put it in first page (now if you take one of the tweaks he has made from scratch that is a different story). I got blamed even when didn't use sources and nothing happened out of it as I gave credits to the sources that Cobrato and I used. Trip is a good developer and just had a bad experience several months ago so give him a break. Even though he has come after me, I understand why he is upset and why he questioned me. He thought I themed his rom and changed things, but I am sure he has figured out I don't need to do that with roms. ENOUGH ABOUT THAT
And to the new chef.. I am going to try this out and will give you some feedback..
why do you post this even when people are negative? because it is about you getting experience with rom's and some people, like me can appreciate learning with your first port of a rom and getting almost no help so I will help you out when I can...
PS people will be negative/positive it happens to me, trip, J, and many others... You just ignore it and do this rom for experience and for yourself.

TripNRaVeR said:
Exactly. They do whatever they like you know, if they want me to stop here so thats really fine be me. Let them working night after night and see what they are getting produced. Other than J, Z and my roms there are only roms that are themed and based on J, Z or my rom. So when i stop just 2 roms left, but whatever if they are happy with 2 roms GOOD. Lots of professional places where i can release roms. And otherwise i'll keep them to myself. Buy a new phone give people who donated me all links to my roms because they know what support and effort means. All others have phone with releasing the same rom over and over again.

Dude why dont u just chill out and anyways i have used j's files and not touched yours but if he has used them i have no idea i just ported normally following drannar's guide and replacing many files by trial and error and gor this thing to work and the camera only works on VGA.. so does J's camera
wolfbreak said:
xd you started it yourself and opened a already done discussion again. If he has the only working camera on 2.3 then he can share it or not becouse he made it himself and if he is sharing it or not is his choice. Trip didnt released sources and theres no credit in first post so if this are trips file then he have no permission to use it. Zdzihu and jerpelea released their sources so thats a other thing but trip didnt so you need to ask him.

Does anyone else know of other roms that will work on our devices? gen 9?

Get Back You Beast!!!! Have you a robot addiction or what? You probably got the wrong device for masses of rom, You should have picked up a Nexus, they pretty much have a rom for each day of the month!! there the CM10 Rom which is usuable
If there's a particular rom you like why don't you have a go at porting it, Folks will help you out if you show some initiative
Also XDA isn't the Biggest forum for archos devices, It's the Best, Obviously because we're all here, ROLF but definitely not the biggest, You might have known French for that
Well I thought I would ask..
I dont really mind that much, Im happy with Surdu`s rom.. I do understand what its like making roms, Im the insanity jb rom maintainer for sgs2, but thats another story

O.K. i see...
Surdu is simply the fastest and seems to build custom ROMs while sleeping
As you see, he created the sticky thread and is very helpful person, that's why he got so dominant on building ROMs.
The best working ROMs are all based on stock... and got more or less customizations.
AOSP and AOKP types (CM as well) are not yet completed, because of the proprietary files inside the Android OS.
There's more reverse engineering to do, to make all peripherals work.
By starting with one of the slim&fast ones from Surdu, you could easily create your own
Simply use a linux host and loop mount the images as ext4.
Depends on the grade of customization, but in most case it would be enough to tweak the system image and leave the kernel+initramfs just in place.

I don't know if i've posted this in the right section, but at times on and off i've thought about doing rom development. When I had a Nexus S 4G I made the attempt of being the first to compile ICS from source for that phone. This phone needs roms, I also can't afford to switch phones. I don't know alot about development, but where could I start so I can begin to learn how to build roms? How difficult would it be to get a rom compiled for this phone that'll boot, being that it has a locked bootloader? If someone can help me so I can at least try to do some type of development for this device. I have to flash some type of custom rom on this phone, lol.
imo the best is a port of cyanogenmod with sources of phones similar to optimus l9 and for sure versions like 4.1 ++
this version of android excisting in optimus l9 ics is working fine. it would be nice porting of newer versions.
Finally someone...first.

Glad and happy to see someone (first one) a developer is willing to work on Source Codes. May be for you only I did collected all the resources.
Source Codes here,
Unrooted Stock Roms here,
Flashing and Rooting here and
Rooted CWM Backups here.
See already collected so much of information so some developer will start working. Did this because the LG links were rapidly dying and still are.
I am not developer, but I will be happy to become a tester for you and would like to try to help you in any way you may want. Happy Developing, BIG THANKS and Best of luck.
I'll start after I get a new ethernet cable for my computer, Ubuntu doesn't work well with my wifi usb adapter. Works fine in Windows and was working ok in Linux Mint, abeit kinda slow. I may have to ask someone for help or for guidance, but i'll try to do something. Better than complaining about no roms but not doing anything to help bring one. I don't know how difficult it would be but I was thinking about building JB from source for this phone?

Hey guys, I haven't forgot. I still don't have any ethernet cable, but my sister let me install Ubuntu dual boot on her laptop. I installed it tonight and using it now so i'm going to set other things up tonight.
Guys, as title says, i'm trying to add otg support in kernel, please flash and use some otg device and confirm whether it works or not.
Dont have time to add proper content, so just note some points:
1. Its for ICS ROMS
2. It might not work
3. Please test with cable and USB Host Diagnostic app from Play Store
4. It might not work
Its built on my neXusKernelv1 so expect the performance and other features to stay intact.

ok, then 2 suggessions,
1. Try with Stock rom.
2. Try using external power source.
I'll try another build tonight. Maybe we need to add something to build.prop and ramdisk also. I'll workk on it.
1. Also not working on stock rom.
2. I don't have usb hub with power source. Or do you mean something else?

I am refering to what the guy above you said.
Actually, the things is, i dont have OTG cable, and i have never used it either. I saw in kernel config that it is configurable, so i want to enable it for those who want it. For that, i will need a dedicated tester to test each release that i make. I will modify some build.prop entries tonight to make it work. Any one willing to spare time for above mentioned thing, please PM me.

It said that i have not support for storage...(i don't know how it looks in original, because I use russian lang. ) I guess, it's mean that kernel does still not provide OTG. на конце палкиBy the way, Sense.Revolution+R1 JB thinks that it phone is on charging when i connecting OTG cable without USB device on the end. Maybe it helps somehow... =))

Usb otg= usb on-the-go. It means that you may connect usb devices(mouse, keyboard, usb flash memory, hard disk etc) to your phone. So you can control your phone using mouse and keyboard, and browse files and folders in your usb memory.

OTG might be a bit more tricky. Im researching on it a bit more.
Anyways, otg or no otg, this thread can be continuation of my neXusKernel. I will be basing future builds on v1 becoz v2 and v3 generally got bad reviews.
Atis112 made some updates on the clock rates of ICS kernel so i will release a build in a few hours.

Yes,i didn't finish it because i stopped all ics projects when jb was here, and im waiting for jb kernel sources now.
does not work for me too
I am on skydragon 2.2
I used an adapter, not sure if it can work that way
will give it a try with a different ROM later today
If i take a look at the Snapdragon specs here:
http://www.qualcomm.com/sites/default/files/common/products-services/snapdragon_specs_9-12.pdf
then i see that the S4 pro/plus specifically include OTG support.
On the other hand, our S4 play indicates 'USB 2.0 HS Peripheral or Host'.
This seems to indicate that it does not support the OTG protocol (which includes a little bit more than just working as usb-host, like automatically figuring out which role to use).
But it also seems that it should be able to work as a USB host. The question remains whether you can select this mode via the kernel or that it is hardwired in the circuitry.
OTG works fine on DX with JB rom. It's mean, that DX is able to support USB-host. May be just need JB sources for porting this feature on ISC?

I think we never will get the JB sources -.-, but maybe we can port it later. Now i s*ck with HW v-sync support. If i can include it to ics kernel sources, people will be able to use official JB with all hboot, and without /system write protection. If it's ready, i will check otg support too
Not sure, if it is possible...
But, due to the fact, that Rebellos is inactive and volk204 obviously stopped development and Tigrouzen also quit ZenDroKat, we have to look for new devs to continue work on Android development on Wave devices...
Next target should be Android 4.4.3...
What do you think?
I am pretty much sure the last developer that is willing to work is both rebellos and volk.
I have one dev here in poland, but No on XDA. I tell him about that )
In my opinion...
Better move is to answer here the truth about further Develpment:

How bout u guys try compiling yourself?
I mean they're already many guides out there, So anyone can learn and compile there own Rom!
And I do t think it makes any point to compile a rom with same bugs etc...
I'd rather focus on fixing present bugs then compiling a new rom,
Anyways, M not being disrespectful or something, but telling u the fact!
But if u guys really want then I can compile Rom, but kernel is a bit complicated for me,
So Team work is best!

Very good idea... but...
I think if some users are waiting, and we waiting very long during all this time...
years.
So maybe it is not wrong, if main Developers could tell us...
discontinued or not...
As you can see, Rebellos for instance, not more talk in public...
...but he is "active" in XDA...
In my opinion it is an question of respect...
We are not married... but it is strange... that so many Devs left project...
But nobody is able to say good bye...

Nobody will kill him.

Compiling is a thing, fixing bugs another.
I can compile ROM or kernel, and changes some in sources for rom and kernel (making Bigmem, SD or Nand kernels for example), but i can't solve any bugs, because it need a knowledge i don't have, and few here have this knowledge...
Well...
I think, we have all abilities...
GT-S85XX are no problem anymore...
GT-S8600 Bootloader is nearly open for Android...
I tihnk, GT-S8600 is a good device to run Android 4.4.3...

Hi adfree
I think it is near end. I can't fix functional kernel issue like charger without Rebellos.

And my USB is completely broken, but i hope i will repair it.

Mr. Volk, if you repair your cable and find time for it, is it possible to put latest updates (GPS, modem etc.) on your 4.1.2 rom for one last time? Your roms was really good. A bit slow but number of bugs are very very small. Because of that I always prefer your roms. Thank you for your all works.

- Could you help us to build Android Kernel on first place, then later ROM for S8600 WAVE3.
Because adfree already hacked bootloader and its opened now for new OS.

After some search, it look like it's "Little" kernel, some kind of bootloader. It load some function (see here for more info : https://www.codeaurora.org/blogs/little-kernel-based-android-bootloader, i don't find lot of doc about it) but i highly doubt it can boot the whole android system.
